Another production for the Symphony of Science series:
A musical celebration of humanity, its origins, and achievements, contrasted with a somber look at our environmentally destructive tendencies and deep similarities with other primates. Featuring Jacob Bronowski, Alice Roberts, Carolyn Porco, Jane Goodall, Robert Sapolsky, Neil deGrasse Tyson and David Attenborough.”

After an initial find of a huge pliosaur on the Artic island of Spitsbergen (see this post) in 2006, scientists are now reporting the discovery of a second specimen:
“Everything we are finding is new to science,” said Jorn H. Hurum, a paleontologist at the University of Oslo who directed the excavations on the Arctic island of Spitsbergen in the Svalbard archipelago. He described new details of the find in a telephone interview last week.
Dr. Hurum said that in the Jurassic Period, Spitsbergen was covered by the then-temperate waters of a deep ocean. In 2006, the expedition began finding a variety of marine fossils, including pieces of the pliosaur skull, weathering out of a mountainside patrolled by polar bears. A year later, the university announced, the team came upon a flipper and much of the first pliosaur specimen.
But only after excavating the second specimen in last summer’s expedition and comparing the two were the scientists prepared to describe their findings about the huge pliosaur’s anatomy and probable physiology and hunting strategy. This was reported in recent science meetings, and Dr. Hurum said a full description would be published next year in a journal.
From the University of Oslo Press Release:
The scientists first hit the headlines in August 2007, when they excavated the skeleton of another pliosaur specimen in the same locality. On the last day of the 2007 expedition, Dr. Hurum spotted large bones in the earth. The team placed a marker, took a GPS reading and returned the following summer to excavate. Little did they realize that this new fossil would be even bigger and more significant than the pliosaur they had discovered the year before.New scientific research reveals that Predator X was approximately 50ft long, weighed in at 45 tons and packed an amazing 33,000lb bite. Its anatomy, physiology and hunting strategy all point to it being the ultimate predator – the most dangerous creature to patrol the Earth’s oceans.

From the BBC:
Five eminent contemporary thinkers write a letter to Charles Darwin to provide us with an intimate understanding of how some modern-day scientists view Darwin’s continuing legacy.
- Dr Craig Venter, one of the men who first successfully mapped the human genome, tells Darwin about his own experiences as a collector, medic and geneticist.
- Sir Jonathan Miller takes issue with Darwin’s thoughts on reproduction and describes the huge advances in the understanding of genetics that have filled the holes in Darwin’s understanding of inheritance.
- Prof Jerry Coyne, whose main research relates to On Origin of Species, tells of the huge body of evidence that has been discovered since its publication to support Darwin’s theory.
- Dr Peter Bentley, who works at the cutting edge of digital biology, tells Darwin about the emerging field of evolutionary computing.
- Prof Baruch Blumberg, who received the 1976 Nobel Prize for his work on viral infection, tells Darwin about his work with the hepatitis B virus and his later work at NASA searching for life on other planets.
